What Claude in Chrome is

From a side panel, Claude reads the current page and can click, type, navigate, fill forms, and work across grouped tabs while you watch. The same extension lets the Claude desktop app and Claude Code drive Chrome, and the listing adds saved sessions, scheduled tasks, and console-log reading for debugging.

Is Claude in Chrome safe to use?

Claude in Chrome comes from Anthropic and is actively maintained, but it is an agent that reads and acts inside your logged-in browser, and its listing discloses six data categories. Anthropic says its prompt-injection defenses reduce but do not remove risk, so use it on trusted sites and keep banking, health, and sensitive work accounts out of reach.

Page access Broad

Requests page-content access across sites. Broad access is not itself a red flag — the question is whether the job justifies the reach, and whether the publisher's record earns it.

Its job requires deep control: Anthropic's help center lists debugger, scripting, tabs, tab-group, webNavigation, and downloads permissions so Claude can read pages, take screenshots, and act. Use "Manually approve" mode to review each step, decline site prompts you don't need, and revoke "always allow" sites on the extension's Permissions page.

Store-disclosed data

  • Personally identifiable information
  • Personal communications
  • Location
  • Web history
  • User activity
  • Website content

The listing discloses six categories: personally identifiable information, personal communications, location, web history, user activity, and website content. Anthropic says Claude takes screenshots of the active tab, so anything visible becomes part of the conversation, and side-panel sessions are saved to your Claude history across devices.

Is Claude in Chrome free?

No. The extension installs for free, but the listing and Anthropic's help center say it is available only on paid plans: Pro, Max, Team, and Enterprise. On Team and Enterprise, an admin can switch it on or off and set site allowlists and blocklists.

Why does Claude in Chrome need so much browser access?

Its job is to act for you. Anthropic lists debugger, scripting, tabs, webNavigation, and downloads permissions so Claude can read pages, take screenshots, click, type, and manage the tabs it works in. Manual approval mode lets you allow or deny each action.

Can a website trick Claude in Chrome?

Anthropic calls prompt injection, meaning hidden instructions in pages, emails, or documents, the biggest risk for browser agents. It screens content and actions with classifiers and blocks some site categories, but says the risk is not zero and advises against using it for financial accounts or medical information.
